Crab Facts: Claws, Shells & Secret Behaviors
Crabs are crustaceans found on every continent with over 7,000 species. Discover why crabs walk sideways, trade shells, and grow claws stronger than jaws.

Parrots are intelligent birds with over 400 species worldwide. Discover parrot talking abilities, problem solving, lifespans, and their complex social behaviors.
Parrots are colorful, intelligent birds belonging to the order Psittaciformes. With over 400 species distributed across tropical and subtropical regions, parrots range from tiny 3 inch pygmy parrots to massive 40 inch macaws.
Parrots are among the most intelligent birds, with some species displaying cognitive abilities comparable to 5 year old children. African grey parrots excel at vocal learning and can understand concepts like color, shape, and number. The famous African grey Alex demonstrated understanding of over 100 words, could count to six, and comprehended zero as a concept. Parrots solve complex puzzles, use tools, and plan for future events.
Parrots are the best vocal mimics in the animal kingdom. They reproduce human speech, other animal sounds, and environmental noises with remarkable accuracy. African greys, Amazon parrots, and budgerigars are considered the best talkers. Individual birds learn 50 to 1,000 words depending on species, training, and individual ability.
Parrots have distinctive curved beaks perfectly adapted for cracking nuts and seeds. Large macaws generate bite forces of 500 to 700 PSI, strong enough to crack brazil nuts. Their upper mandible is hinged to the skull, providing exceptional leverage and flexibility. Their strong wings enable fast, direct flight at 40 to 50 mph.
Parrots are highly social birds that live in flocks ranging from dozens to thousands of individuals. They form complex social hierarchies and lifelong pair bonds. Mated pairs preen each other, share food, and remain together constantly. Each individual has a unique contact call that functions like a name.
Most parrots are omnivores that primarily eat seeds, nuts, fruits, flowers, and nectar. Some species specialize. Lories and lorikeets have brush tipped tongues for collecting nectar and pollen. Kea parrots from New Zealand are highly opportunistic, eating insects, carrion, and even attacking sheep.
Females lay 2 to 8 eggs. Incubation lasts 18 to 30 days with both parents participating in most species. Young develop slowly, fledging at 8 to 12 weeks. Small budgerigars live 5 to 10 years while large macaws can reach 50 to 80 years.
Ancient Greeks and Romans kept parrots as status symbols, prizing their speaking abilities.
European explorers brought parrots from the Americas starting in the 1500s, sparking exotic pet demand.
Alexander the Great's armies brought parakeets to Europe from India around 327 BC.
Parrots were among the first birds to demonstrate tool use and problem solving to scientists.
The study of parrot cognition revolutionized understanding of bird intelligence and consciousness.
Dr. Irene Pepperberg's 30 year study of Alex proved parrots understand language, not just mimic.
Research showed parrots have unique brain structures for vocal learning similar to humans.
Studies revealed parrots can understand abstract concepts like zero, same, and different.
Scientists discovered parrots have individual names in the form of unique contact calls.
Research proved parrot vocal learning involves the same neural pathways as human speech.
Pirates and parrots became inseparable in popular culture through Treasure Island and media.
Parrots rank among the most popular pet birds worldwide despite high maintenance needs.
Conservation campaigns highlight parrot intelligence to advocate for wild population protection.
Parrot rescue organizations address the problem of surrendered birds that outlive owners.
Social media has made parrots viral sensations for their speaking and dancing abilities.
Before the pet trade and habitat destruction intensified in the 20th century, parrot species flourished across tropical and subtropical regions worldwide. Dense rainforests supported diverse parrot communities that played crucial roles in seed dispersal and forest regeneration.
After decades of illegal trapping and deforestation, over 100 parrot species now face extinction. Some species like Spix's Macaw have gone extinct in the wild. Conservation breeding programs struggle to maintain genetic diversity. However, protection efforts have stabilized some populations, and research on parrot intelligence has increased public appreciation for their conservation.

Alex understood zero. The famous African grey parrot comprehended the concept of nothing before any other non human animal.
They name their babies. Parrot parents give chicks unique contact calls that function as names throughout life.
Parrots can taste with their feet. Their feet contain taste receptors that help evaluate food while perching.
Some parrots attack sheep. New Zealand's kea parrots are opportunistic omnivores known to attack sheep for fat.
They see ultraviolet light. Parrot feathers have UV patterns invisible to humans but used for mate selection.
Kakapos are the only flightless parrots. These endangered New Zealand birds can weigh over 9 pounds.
Parrots mimic human speech using their syrinx, a specialized vocal organ. They do not have vocal cords like humans. While mimicry is remarkable, most parrots repeat sounds without understanding. However, some species like African greys demonstrate contextual understanding, using words appropriately. Individual birds learn 50 to 1,000 words. African greys, Amazon parrots, and budgerigars are the best talkers.
